碩士 === 國立交通大學 === 資訊科學系所 === 93 === Along with the evolution of the communication technology, more and more data in our daily life are transferred and exchanged on internet or other communication equipments. Therefore, dealing with data on the internet becomes the problem solved in need of the computer operation system. Problems in this aspect were handled by general CPU, but nowadays the situation has changed. NPU is developed to offer high speed packet switching in order to solve the daily increasing internet flow problem. And there are more and more requirements both on information encrypted system and data transformation on internet. In this thesis, shortening the encryption time of general CPU or internet processor by foresighted secure module chip and personal trust device are proposed. Mobile communication devices such as PDA and cellular phone will be inalterable and credible by installing the PTD (Personal Trusted Device). The secure module chip is the combination of mathematical calculations such as Symmetric Key Cryptosystem, Public Key Cryptosystem, Message Digest, signature and random number generator, and is capable to offer functions like encryption, decryption, certification and signature. Further more, the safety module chip enable the PTD to perform encryption, decryption, certification and digital signature, and become a concrete device or vehicle under PKI (Public Key Infrastructure).
